On stage, Christa Ludwig's Leonore puts all others in the shade. In this role, she achieves something rare: a perfect unity of stage character and singer. Her male disguise is believable; this Fidelio is a slender, lanky young man with whom it is easy to imagine the silly Marzelline falling in love.

Desdemona in Verdi's Otello was a career role for soprano Renata Tebaldi, from her first operatic performance outside of Italy to her final appearance on the opera stage. Between those landmarks she performed the role nearly 100 times all over the world and made studio audio recordings that became reference recordings for the role. This 1962 production with the Deutsche Oper Berlin and Giuseppe Patane was planned as a media event from the outset and blessedly captures a consummate artist in a signature role at the peak of her gifts.
